Previously, we used the default character encoding from the project properties to determine how strings and character constants in the entire source file should be encoded. Now we switch between encodings as needed. The default character encoding is no longer relevant. High ASCII is now an actual encoding, rather than acting like ASCII that sometimes doesn't work. Because we can do high ASCII character operands with "| $80", we don't output a .enc to switch from ASCII to high ASCII unless we need to generate a string. (If we're already in high ASCII mode, the "| $80" isn't required but won't hurt anything.) We now do a scan up front to see if ASCII or high ASCII is needed, and only output the .cdefs for the encodings that are actually used. The only gap in the matrix is high ASCII DCI strings -- the ".shift" pseudo-op rejects text if the string doesn't start with the high bit clear.
